Are mushrooms good for you? Interestingly, fresh mushrooms might be the world’s most underestimated and underappreciated food. Most people view mushrooms as a vegetable, but they are instead a type of fungi. It can be bad for you if you accidentally consume poisonous wild mushrooms. In addition, these varieties can be challenging to determine in the wilderness. Therefore, only consuming mushrooms are purchased from reliable grocery stores.
Here are the top seven benefits of eating mushrooms, nutrition facts, preparation tips, and how to serve mushrooms.
Are Mushrooms Good For You?
Are mushrooms healthy? In a meal, mushrooms work to create rich and savory dishes ranging from everyday affordable side dishes to costly and decadent main dishes. They can also provide an excellent accompaniment to any meat, fish, soup, salad, risotto, or cheese.
Yet, many throughout history have considered them a superfood, and practitioners have used mushrooms for thousands of years because of their healing and medicinal properties. Plus, they pack a big nutritional punch.
Surprising Benefits Of Mushrooms
In the grocery store, you will find that it comes in a variety of shapes and sizes, all with unique flavor profiles. All mushrooms are good for you because they contain low calories and fat yet include fiber, vitamins, and minerals. Perhaps the most interesting nutritional aspect of mushrooms is their plant substances which include
- Polysaccharides
- Polyphenols
- Indoles
- Carotenoids
Why mushrooms are good for you? Studies have shown these plant compounds to be powerful antioxidants with anti-inflammatory properties. In addition, they can prevent various diseases, including cancer.
Improve Brain Health
Mushrooms are rich in polyphenols. Polyphenols are compounds found in plants that have protective qualities. For example, a study[1] published last year found that polyphenol-rich foods (mushrooms, red wine, coffee, etc.) are associated with cognitive preservation.
This is thought to be due to protective compounds in diets rich in polyphenols and their benefits to gut microbiota and metabolism, which help preserve cognitive health. In 2020 a meta-analysis[2] was performed and evaluated the effects of a polyphenol-rich diet on the cognitive health of young and middle-aged adults.
The results found a good correlation between polyphenol-rich interventions and improved cognitive functions—specifically, the brain’s neural networks’ ability to change through growth and reorganization.
Cancer Prevention
Edible mushrooms are very high in antioxidants and indoles. Antioxidants are our body’s ally against free radicals. Free Radicals are unstable molecules that can cause diabetes, cardiovascular disease, and cancer if they become too abundant.
Indoles[3] are a phytochemical type mainly associated with a reduced risk of cancer. Cancer is the leading cause of mortality worldwide, accounting for almost 15% of deaths worldwide.
Per the National Cancer Institute, a diet high in antioxidants can help prevent many cancer tumor cells, including prostate, lung, and breast cancer cells.
If you have cancer and are undergoing treatment, antioxidants (like the ones in mushrooms) also have a place. An analysis[4] published in 2018 evaluated 174 peer-reviewed studies, 93 clinical trials, 56 animal studies, and 35 in vitro studies.
This data concluded that antioxidants have a superior potential for eliminating chemotherapeutic-induced toxicity. Also, antioxidant supplementation during chemotherapy promises higher therapeutic efficiency and increased patient survival rates.
Portobello mushrooms and oyster mushrooms are especially good for you when it comes to cancer prevention as they hold the highest amount of antioxidants.
Improve Gut Health
The gut microbiome is a unique ecosystem of bacteria and organisms in your digestive tract. A healthy microbiome (one with a good balance of good and bad bacteria) has been linked to fantastic benefits such as a robust immune system, mood stability, mental health, and improved digestion.
On the other hand, an unhealthy[5] microbiome can lead to
- Anxiety
- Depression
- Mood instability
- Chronic gut discomfort
- Diarrhea or constipation
- Bloating
- Fatigue
- Auto-immune disorders
One way to ensure a healthier gut microbiome is by eating prebiotics. Prebiotics are various fibers and natural sugars that promote the growth of beneficial bacteria in your intestines.
Research shows the natural sugar (polysaccharides) found in mushrooms is a potent prebiotic that stimulates the growth of healthy gut bacteria.
Unfortunately, most natural sugars are destroyed when they come into contact with stomach acid. However, the polysaccharides in mushrooms can withstand stomach acid and reach the colon, encouraging healthy bacteria growth. The mushrooms with the highest levels of polysaccharides are reishi and maitake.
Improve Heart Health
Mushrooms contain about 5% of your daily needs for potassium. Potassium[6] is a mineral essential for heart health, healthy blood pressure, and regulating the circadian clock in human red blood cells.
Studies have shown that increasing potassium can lower the risk of heart attack, stroke, and heart disease. This is because potassium helps prevent plaque buildup in the artery walls (atherosclerosis), which causes high blood pressure. This is the number one cause of a stroke as plaque buildup in the arteries narrows blood flow.
One study[7] published in 2017 gave mice a low or high-potassium diet and a high-cholesterol diet. The mice who consumed a low potassium diet showed a more significantly increased calcification and artery stiffness than those who were given the high potassium diet.
White mushrooms are especially good for you regarding potassium. White mushrooms, which account for about 90% of the mushroom consumption in the U.S., have the most potassium at 300 mg per serving.
More studies[8] need to be completed, but a dietary fiber called beta-glucans may help lower cholesterol.
Further, they might be able to develop a way to treat patients with dyslipidemia. This would be exciting as they are naturally occurring and, therefore, don’t have adverse side effects.
Certain mushrooms, such as shiitake mushrooms (especially the stem)[9], are specifically good for you in this regard as they are a great source of beta-glucans.
Boost Immune Health
Mushrooms are rich in polysaccharides[10], as discussed earlier. These polysaccharides can increase the number and variety of beneficial bacteria in the gut.
These healthy bacteria can do several different functions that benefit our immune system, such as
- Promote Anti-inflammatory activity
- Enhance intestinal barrier
- Activate immune cells
- Regulate immune cells
These functions are vital for improving and maintaining a healthy immune system. Of note, canned mushrooms are not good for you in this respect as the polysaccharides are structurally altered by their food processing[10] conditions.
High Choline Sources
It is difficult to get enough choline in your diet if you are a vegan. High choline sources include red meat, liver, egg yolks, chicken, and fish. Choline plays an integral part in many bodily functions, such as
- Cell integrity and support[11]
- Making, transporting, and metabolizing fat
- DNA synthesis
- Heartbeat regulation
- Muscle Movement
- Memory
- Nervous system health
Mushrooms are a great vegan source of choline. For example, one entire cup of shiitake mushrooms contains about 20% of your daily choline needs.
High Amounts of Vitamin D
Vitamin D[12] is another nutrient that is tough to obtain from plant foods. Besides animal products, the only way to get vitamin D is through mushrooms, sunshine, fortified milk, and cereals.
Vitamin D is essential for your health as it provides the following functions in the body
- Absorbs calcium to maintain teeth and bone health
- Supports good immune function
- Supports healthy bone mineralization
Like us, it exposed to UV light (sunlight) enrich their vitamin D levels. White button mushrooms are especially good for you regarding vitamin D levels as they attract and possess the highest vitamin D levels after exposure to sunlight.
For the most significant amount of vitamin D, expose white button[13] mushrooms to sunlight for a minimum of 15 minutes before eating. Of note, maitake mushrooms naturally have high amounts of vitamin D without needing to be exposed to sunlight.
